Beetle - Anaspis flavipennis

Beetle - Anaspis flavipennis
Tippecanoe County, Indiana, USA
April 19, 2006
Size: 2.75 to 3 mm
Not sure exactly what this is. Had placed it with my Mo*rdellidae, but it lacks the tibial ridges and apical abdominal spine.
Just by guessing, I imagine its in the Meland*yridae. The best I can come up with is Orch*esia o*vata, but I am still not too sure. Any ID help appreciated.

Beetle - Anaspis flavipennis Beetle - Anaspis flavipennis

Moved from Flavipennis.



check for Scraptiidae
. . . tarsal formula (as in Mordellidae): 5,5,4.

Leiodids may have various tarsal formulas, but will not have this one.

Cholevinae always have remarcable antennae: 5-segmented club, with the second club segment always much smaller than the 1st and 3rd.

thanks in advance, Boris

This guy does have 5-5-4 tarsal formula. I was wondering why it didn't have a small 8th antennomere. Obviously my attempt to key it within the Leiodidae was unsuccessful. This is good though because now I've learned the difference between these two groups.

So because of the transverse striga on the elytra, this is subfamily Anaspidinae. Genus is Anaspis because of gradually thickened antenna. Coloration matches that of Anaspis flavipennis. I also just caught what is a male of this species last week and it has the two moveable appendages on the 3rd abdominal segment.

Thanks Boris!

Leiodidae: Cholevinae
I would guess Catops americanus, but it would be purely a guess based on color and size - the picture is too small for any significant details.

Thanks. This gets me a lot closer. Leiodidae was completely off my radar. Will see if its possible to narrow down.

not O. ova*ta
Compare with this one that Don Chandler says might be O. ovat*a.
